在股票市场中，有些股票前面会加上“R”，这个“R”代表的是人民币股票。在中国，上市公司的股票是按照币种分为人民币股票和人民币特种股票。人民币股票简称为A股，是以人民币标明面值、以人民币认购和进行交易的普通股票，它的主要特点是只允许我们中国人用人民币进行买卖。与之相对应的是B股，它是以人民币标明面值、以外币认购和进行交易的特种股票，可以让我们中国人用外币进行买卖。

在A股市场中，我们可以看到很多股票前面都会加上“R”，这个“R”代表的是人民币股票。它的主要特点是只能在A股市场进行交易，不能进行跨市场交易。同时，人民币股票的风险相对较小，因为它的价格波动相对较小，而且受到的监管也相对较少。

总的来说，股票前加“R”代表的是人民币股票，它的特点是在A股市场进行交易，风险相对较小。

In the stock market, some stocks are prefixed with "R", which represents the Chinese currency stock. In China, the stocks of listed companies are divided into Chinese currency stocks and Chinese special currency stocks by currency. Chinese currency stocks, referred to as A-shares, are ordinary stocks denominated in Chinese currency and can only be purchased and traded in Chinese currency. The main feature of A-shares is that they can only be traded within the A-share market and cannot be cross-marketed. At the same time, the risk of Chinese currency stocks is relatively small because their price fluctuations are relatively small and they are less regulated.

In the A-share market, we can see that many stocks are prefixed with "R", which represents Chinese currency stocks. The main feature of Chinese currency stocks is that they can only be traded within the A-share market and cannot be cross-marketed. The risk of Chinese currency stocks is relatively small.
